The Michigan Department of Natural Resources required an emissions control measure during the closure of an Ann Arbor Solid Waste Landfill cell. The odors that were emanating from the landfill during the grading process were so severe that residents in the adjacent neighborhood complained to the City of Ann Arbor on a constant basis.

Rusmar Incorporated's AC-645 Long Duration Foam was applied to the surface immediately behind each of the graders. The AC-904 Long Duration Foam was utilized to control odors for periods up to two weeks during holiday shut downs and for weekend coverage. Rusmar Incorporated's Long Duration Foam was so effective in controlling odors, neighborhood complaints to the City of Ann Arbor ceased immediately upon the first application of foam.

For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires can float like balloons to the surface, sometimes rupturing the protective liners that keep contaminants from polluting...

One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints.
In fact, compared to other industrial applications such as wastewater treatment and asphalt production, landfills face more challenges in fighting odors. Moisture, humidity, agitation, and summer temperature can...
